The Dr Debug codes you're getting relate to PCIe initialization (10) and RAM module initialization (15, 19). Since it is stopping at 19, I'm going to suggest you check your ram modules to ensure they are firmly seated. You might try booting with one stick only, swapping them until either 1) you get a good POST or 2) you go through all modules without a good POST. Also, check your graphics card to ensure it is seated properly.
Let me know what happens...
